Please clarify what you mean by Central Govt. Agency. The Payment of Gratuity Act being discussed in general in this forum is not meant for government departments, but it shall cover public sector units. Therefore, if you have been working in any government service on a fixed-term or temporary arrangement, you may refer to the service rules to know whether you are eligible for gratuity or not.
Applicability of Payment of Gratuity Act for Employees Under Fixed-Term Contract
The artificial breaks of a few days will not make the employee ineligible for gratuity. However, there are a few things to be observed.
One, there should be a minimum of five years' service from the date of joining till the date of exit.
Second, the service should be continuous or uninterrupted. Each year of 12 months shall have at least 240 days' working in order to make it uninterrupted. Obviously, a break in service of 4 to 5 days will not make it interrupted.
Third, extending the 240 days concept to the fifth year, some High Court judgments say that if an employee has rendered 4 years and 240 days in the fifth year, he will be eligible to get gratuity. This is still a question of law because under the Payment of Gratuity Act, it is still 5 years, and the matter of 240 days is purely technical to decide whether an employee has continuous service or not.
Four, for calculating the amount of gratuity, which is based on the last salary drawn and the length of service, a fraction of service of more than 6 months shall be rounded off to one year, and any fraction of less than 6 months shall be ignored. This does not mean that a service of four years and more than 6 months in the fifth year would make an employee qualify for gratuity. Under both high court verdicts, Kerala High Court's Shreeja Vs RJLC or Madras High Court's Mettur Bearsel's case, only 240 days in the fifth year has been granted as one year. Therefore, even if adapting these high court decisions, a minimum service of four years and 240 days is mandatory.
